The DSC1033DI1-024.5760T is a MEMS-based XO (Standard) from Microchip's PureSilicon™ series, delivering a 24.576 MHz CMOS output from a 3.3 V supply rail. A 24.576 MHz clock is common in digital audio (sample-rate conversion), Ethernet PHY reference, and FPGA transceiver PLLs — the stability budget is adequate for these interfaces, though a ±25 ppm or tighter part would be needed for precision timing protocols like IEEE 1588. The active current is 3 mA typical — low enough for a shared 3.3 V rail on a mixed-signal board.
Microchip lists the DSC1033DI1-024.5760T as obsolete. No official successor part number is published by the manufacturer for this exact frequency and package. For new designs, a current-production MEMS oscillator in the same 2.50mm x 2.00mm 4-SMD footprint should be evaluated — the pad pattern is common across many vendors, so a board spin is not necessarily required if the replacement matches the pin function and supply voltage.
Package and temperature grade – board-fit checklist
4-SMD no-lead package, 2.50mm x 2.00mm body, 0.90mm seated height max. The four pads are: pin 1 (standby/disable), pin 2 (ground), pin 3 (output), pin 4 (Vdd). The 0.098" x 0.079" footprint is shared by many MEMS and crystal oscillators — verify the pad layout against your existing land pattern before committing. The 3.3 V supply is standard for modern SoCs and FPGAs; no level translation is needed on the output if the receiving logic is 3.3 V tolerant.
